2.3 Risks resulting from non-observance of the
safety instructions
Non-observance of the safety instructions may cause
hazards to persons and the environment or damage
to the hand extruder. Moreover, failure to observe
the safety instructions may lead to the forfeiture of
any damages.
Non-observance of the safety instructions may in
particular involve the following risks:
•
failure of important hand extruder functions,
•
hazards to persons due to electrical and
mechanical impacts including risk of burns,
•
hazards to the environment due to vapour-phase
hazardous substances,
•
risk of fire.
2.4 Safe working practices
The safety instructions given in these operating
instructions, the applicable national accident
prevention regulations and any existing in-company
work instructions, operating and safety procedures
issued by the Operator must be followed.
2.5 Safety instructions for Operator / operating
personnel
•
Before placing the hand extruder in service,
check the mains voltage and frequency against
the data indicated on the type tag. The allowable
tolerances are ± 5 % for voltage and/or
±
2 % for
frequency.
•
According to VDE 0100 §55, the hand extruder
must be operated via a residual current-operated
circuit breaker or an isolating transformer.
•
CAUTION During hand extruder operation (under
load), a voltage of not less than 230 V
1)
must be
available at the connector of the hand extruder.
•
When using an extension cable, make sure to
observe the minimum conductor cross-section.
Use extension cables with protective conductor
only.

2.1 Identification of information in the operating
instructions
In these operating instructions, safety instructions
whose non-observance may cause hazards to
persons are identified with
Hazard symbol according to DIN 4844 – W 9
for general hazards and with
Hazard symbol according to DIN 4844 – W 8
for electrical hazards.
Safety instructions whose non-observance may
cause damage to the hand extruder and its functions
are marked with
CAUTION
Instructions directly indicated on the hand extruder
must be strictly followed and kept in a fully legible
state.
2.2 Personnel qualification and training
The operating, maintenance and inspection
personnel must possess appropriate qualification for
the work to be performed. Functional and technical
responsibilities and supervision of the operating
personnel must be clearly regulated by the Operator.
Where the personnel do not have the necessary
skills and knowledge they must be trained and
instructed (e.g. a DVS basic welder training in
extrusion welding). A detailed instruction into hand
extruder operation will be provided by the
Manufacturer/Supplier on request. Furthermore, the
Operator has to make sure that the contents of the
operating instructions is fully understood by the
operating personnel..
